Re: [gentoo-dev] new net runlevel

There is probably a way to do what you are asking with the init runlevels. It 
might take more effort than it is worth.

I might offer an alternative. You should be able to set your own bootparam and 
add entries to your /boot/grub/menu.lst to pass different bootparams. E.g you 
might have an entry where the kernel line looks like this:

kernel bzImage root=/dev/hda3 myoption=nonetwork

Then at boot time, you would select either the network or the non-network 
boot.

To implement this, you would just customize the desired init scripts to check 
for that flag and initialize accordingly. Init flags get stored in 
/proc/cmdline, so you could grep it to see if the nonetwork flag was set. To 
give you some idea....

#!/bin/bash

if [[ `grep "myoption=nonetwork" /proc/cmdline` ]]; then
    # do whatever you need to do with no network
else
    # do what you need to do with network
fi

Hope that gives you some ideas,

Matt
